Hi, am Rupreet, new to this place but have decent software engineering experience. I came here to participate in bug fixing so that I can understand this language better. Are there any low hanging issue which I can pick up?

Welcome! If you're interested in working on the compiler, then issues labelled E-mentor are a a great place to start. You can assign an issue to yourself my commenting @rustbot claim and can always ask for help on the issue or in #t-compiler/help.
